The stock computer is tuned for 87 octane. Of the 2005-2009 Mustang GT's only the Bullit models will advance timing with higher octane gasoline with the stock programming. The Bullits are programmed for 91 octane gasoline and come with the Ford Racing Performance Parts cold air intake stock. The Bullit models will change the timing back to stock if you use 87 octane gasoline. Running 93 octane will cost me more money and not give me any more power. I tried running 89 octane for a few tanks to see if it would increase the gas mileage, but it actually went down.
Some of the aftermarket tuners offer 91 and 93 octane programs that can be flashed into the stock computer. I saw a dyno of one of the tuner's 93 octane street tune give a gain of 13-15 HP on the dyno. They also offer 93 and 94 octane race tunes. The Cold air intake I have fromthe silver car comes with a 91 octane tune for the intake.

I might go this weekend. I was planning to go last week to Island Dragway on Friday, but it rained. I want to run it stock once or twice before I modify it.
